Description

Technical Field

[0001] This utility model relates to the field of Dunaliella salina cell technology, specifically a high-throughput screening device for Dunaliella salina cells. Background Technology

[0002] Dunaliella salina cells are a type of single-celled eukaryotic algae belonging to the phylum Chlorophyta, class Chlorophyta, order Volvoxales, family Dunaliellaceae, and genus Dunaliella. Dunaliella salina cells lack a cell wall, are enclosed by glycoproteins, and exhibit diverse morphologies, commonly including pear-shaped, elliptical, and long-necked bottle-shaped cells. The cells are approximately 14–22 micrometers in length and 3–14 micrometers in width. They primarily reproduce asexually, dividing into two daughter cells along their longitudinal axis when nutrients are plentiful; and sexually when nutrients are insufficient, forming a zygote that develops into a new cell. Dunaliella salina cells are rich in various nutrients, such as proteins, vitamins, and minerals, which are beneficial to human health.

[0003] However, when screening existing Dunaliella salina cells, the Dunaliella salina and culture medium need to be filtered. However, the existing equipment is inconvenient to use and may require repeated filtration. The operation is cumbersome, and the Dunaliella salina may become clogged during filtration, resulting in slow separation and reducing the work efficiency of the staff. Utility Model Content

A bearing B33 is installed on the top of the top cover 3. A spur gear 34 is installed on the top of the bearing B33. A long rod 35 is connected to the bottom of the spur gear 34. A scraper 36 is installed at the bottom of the long rod 35. A support rod 5 is installed on the left side of the top cover 3. A motor 50 is installed at the other end of the support rod 5. A main gear 51 is installed on the output shaft of the motor 50.

[0020] To facilitate disassembly of the connecting cylinder 4 via a threaded connection, in this embodiment, preferably, the top cover 3 has round holes A30 at both ends of its top, the bottom of the top cover 3 is connected to the connecting cylinder 4, the top of the connecting cylinder 4 has threaded rods 40 at both ends, the surface of the threaded rods 40 is connected to threaded plates 41, the bottom of the connecting cylinder 4 has a filter screen 42, the connecting cylinder 4 is located inside the outer shell tank 1, the threaded rods 40 pass through the inside of the round holes A30, and the top of the threaded rods 40 is threadedly connected to the bottom of the threaded plates 41.

[0021] In order to facilitate the vertical displacement of the movable plate 2 driven by the lead screw 12, in this embodiment, preferably, the lead screw 12 passes through the rod hole 20, and the lead screw 12 is connected to the movable plate 2 by the lead screw. A fixing rod 6 is installed at the bottom of the right limiting groove 10, and the fixing rod 6 passes through the rod hole 20, and the rod hole 20 is slidably connected to the fixing rod 6.

[0022] In order to facilitate the meshing of the main gear 51 and the spur gear 34, in this embodiment, preferably, a column hole 32 is provided on the left side of the top cover 3, the square column 14 is slidably connected to the column groove 13, the square column 14 passes through the column hole 32 and is fixedly connected to the main gear 51, and the main gear 51 and the spur gear 34 mesh with each other.

[0023] In order to facilitate the spur gear 34 to drive the scraper 36 to scrape away the blockage of the filter screen 42, in this embodiment, preferably, the top cover 3 has an inlet 7, the bottom of the spur gear 34 is equipped with a locking post 38, the top of the long rod 35 has a locking groove 37, the locking post 38 passes through the round hole B31 and engages with the locking groove 37, and the bottom of the scraper 36 is in contact with the top of the filter screen 42.

[0024] It should be noted that, in the operation of a high-throughput screening device for Dunaliella salina cells, the Dunaliella salina and nutrient solution are first poured into the inlet 7 and flow into the connecting cylinder 4. Then, the motor 50 is turned on, causing the motor 50 to drive the main gear 51 to rotate. Since the main gear 51 meshes with the spur gear 34, the rotation of the main gear 51 simultaneously drives the spur gear 34 and the square column 14 to rotate. The rotation of the square column 14 drives the lead screw 12 to move the moving plate 2 upward. Then, the liquid flows into the outer shell tank 1 through the filter screen 42. The algae adhere to the surface of the filter screen 42. The spur gear 34 drives the long rod 35 to rotate, which in turn drives the scraper 36 to rotate and scrape away the algae, preventing the algae from clogging the filter screen 42. Then, the operator holds the outside of the connecting cylinder 4, rotates the threaded plate 41 to separate it from the threaded rod 40, and moves the connecting cylinder 4 downward to remove it. At the same time, the long rod 35 also moves downward to separate the slot 37 from the locking post 38. Then, the connecting cylinder 4 and the long rod 35 can be removed, and the algae can be poured out. The same process is followed during installation to complete the operation.
